ThatDarkFellow:Why did the trucks explode? Was this intentional or am I missing a part of the story?

They were loaded down with filled 5 gal. propane tanks. Wherever the fire initially started, it got to thetrucks and that's all she wrote. I'm just hoping that the fire stays away from the larger storage tanks.

From what they're saying on the live feed is that the semis near the plant were full of empty propane tanks, the kind you use with a propane barbeque, but that there's enough residue inside each one of them to make them explosive. One of the things the plant does is fill those propane tanks.

Good to see some lessons from West, TX being applied so quickly, that firefighters are keeping defensive positions and only moving in so far as they are certain they can get pulled back out. Hopefully casualties can still be kept to a minimum.
